Lindsey Graham. A man with absolutely no dignity or spine, but is good enough at playing the game that he gets a "reasonable" label because he'll occasionally call out someone on his side.
I think Peak Lindsey came out a few weeks ago when he apparently went on some Fox show to basically beg viewers to donate to Trump so he could apparently afford to fight back against his court cases. One of those "Awwww, someone is hoping to be his little sidekick buddy if he proves electable again in '24" moments.
